Powerflushing a system prior/post
to any work being carried out on a central heating system is now a
requirement set out by all boiler manufacturers. This is a process
where water and chemicals are pumped through your pipework at a
very high velocity (Not high pressure), and this will have the
effect of removing any flux residue and also the iron oxide (Black
Sludge) that is prevalent in every central heating system. This
process will help to eliminate any radiator cold spots and will
also dispose of any residue that could potentially damage your new
boiler and invalidate the guarantee. This process will not rectify
faults that occur through having a badly designed system (Pumping
over etc). If you have an Open Vented System with a header tank in
the loft, or a Combination System then this process has the
potential to show up any weak points in your system and could
result in leaks occurring from old pipes and/or radiators that are
either rusted or badly fitted.

Please note
the Powerflushing process has not caused this damage
but it has simply accelerated any problems and leaks that may occur
in the future, and this could be while you are absent from the
house possibly on a holiday. It is in our experience that if this
is to happen it is better that a qualified heating engineer is
present to rectify these problems if/when they occur. We do pride
ourselves on usually being able to pick up any potential weak spots
on a heating system prior to any work being carried out, but this
can’t be guaranteed. AMR Plumbing & Heating Ltd cannot be held
in any way responsible for any damage that occurs during this
process.
